WILLIAM L. RAWLES, OF SOUTH NORFOLK, VIRGINIA.

WASHER-CUTTER.

Application filed February 19, 1917.

To all whom it may concern:

Be it knownthat 1, WILLIAM L. RAWLEs, a citlzen of the United States, residing at South Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Washer- Guttersand I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to anew and very simple but useful tool for the cutting of washers or gaskets from leather, paper, and other materials ordinarily em-- ployed therefor, upon carriages, wagons, for pump packing, and many other various purposes too numerous to herein enumerate, and which are well known to all conversant with mechanics. The principal object of the invention is to provide a tool of this character which is adjustable to cut washers or gaskets of vary ing sizes within certain limits.

A further object of the invention is to provide an improved means for adjusting the cutters of a tool of this character.

An additional object is to provide a clevice of this character which will be simple, strong, durable and inexpensive in construction, eflicient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

The accompanying drawings represent the preferred form of the invent-ion, wheren.

Figure 1 is a side elevation of the device;

Fig. 2 is an end elevation of the same;

Fig. 3 is a vertical sectional view taken on the plane of the line 33 of Fig.

Fig. 4 is a similar view taken on the plane of the line 44 of Fig. 1;

Fig. 5 is a vertical sectional view taken on the plane of the line 55 of Fig. 3;

Fig. 6 is a similar view taken on the plane of the line 66 of Fig. 1; and

Fig. 7 is a bottom plan view of one of the sliding blocks.

Referring more particularly to the drawings, the reference numeral 1 designates a substantially cylindrical horizontal member Specification of Letters Patent. Patgntgd Sept. 25 191% Serial No. 149,556.

or beam having a substantially semi-cylindrical shaped longitudinally extending groove 2 in its upper side, and a rectanguiar shaped longitudinally extending groove 3 in its lower side. Slidably mounted on the beam 1 is a trio of sleeves or blocks 1, 5 and 6. The block 6 forms the body portion of an upright member or spindle 7, the la tter being so constructed to fit into the socket, or jaws of an ordinary drill press or other rotating member, thus imparting motion to the same. Extending downwardly from the block or body member 6 is a boss 8 having an opening or socket 9 in the lower end thereof. Arranged within the socket 9 is a center pin 10, the latter being clamped removably and adjustably in place by a clamp ing screw 11 which extends through one side of the boss 8 as clearly shown by the drawings. Extending horizontally from the block or body portion 6 is an additional boss 12 having a clamping screw 13 extending vertically through the same and engaging the groove 2 in the beam 1 to lock said block 6 rigidly to the beam when it is in its proper or desired position. The lower interior side of the block 6 and boss 12 is provided with a longitudinally extending groove 14 disposed in alinement with the groove 3 in the beam 1, and disposed in these alined grooves 3 and 1 1 is a key 15, the latter serving to prevent the block 6 from rotating with respect to the beam 1, as will be readily understood.

The slidable blocks 4 and 5 are identical in construction and are each provided with bosses 16 extending upwardly from the upper side thereof, said bosses 16 having clamping screws 17 extending vertically therethrough and engaged with the groove 2 in the beam 1 to lock said blocks 4 and 5 in their adjusted positions on the beam. Extending horizontally and preferably from the outer ends of the blocks 4 and 5 are bosses 18 having grooves 19 in their lower interior sides in alinement with similar grooves in the lower interior sides of the blocks 1 and 5 to receive keys 20 which prevent rotation of said blocks upon the beam. Extending downwardly from the lower exterior sides of the blocks 4 and 5 are additional bosses 21, the latter having upright sockets or openings 22 therein for receiving the upper ends of suitable cutters 23 and 23. Extending diagonally through one of the sides of the bosses 21 are set screws 24,

the lower ends of which bear against the upper ends of the cutters 23 and 23, and when actuated move said cutters vertically, thereby adjusting the same, as will be readily understood. After the cutters have been adjusted, they are locked in position by suitable screws '24 which extend horizontally through another side of the bosses 921, as shown.

Thesecutte'rs may be of various dorms-and shapes according to the character of the material from which the washers or gaskets are to be cut. The cutter 23 is beveled on both of its sides and is provided with a rounded nose, while the cutter 23 is cut away on one of *itssidesfonly, leavinga broad lower edge which -is slanted upwardly from its forward to its rear side. This latter cutter is obviously much stronger than the former'and is designed for cutting ma terial of 'a tougher nature than that to be cut by the former cutter.

In using this device, the spindle 7 is inserted in the socket of thec'huck of the drill press as hereinbefore described. As the chuck is moved downwardly in the usual manner and rotated, the center pin 10 engages the material from which the washer is to be cut and serves to steady the rotating device as well as to hold the material in place. As the blocks 4 and 5 are disposed on opposite sides of the block 6, spindle 7 and center pin 10, and at difieren-tdistances therefrom, they will be brought into engagement with the material and will scribe and cut concentric circles therein and coinple'tely through the same as the *drill chuck is moved further downwardly. It is obvious that when it is desired to cut washers or gasketsofother sizes, it is only necessary to loosen the sdrews 17 and slide the blocks 4: and 5 longitudinallybn the beam 1.

From the foregoing description, taken in connection with the accompanying drawing's, the construction operation of the device will be readily understood without a more extended explanation.

As yarious changes in form, proportion, and minor details of eonstructionm'ay be re sorted to without departing from the spirit of this'inventioml do not wish to be limited to the construction herein shown and described other than that set forth in the appended claim.

I claim:

A device of the class described compris ing a member atla teal to be r'ota-ted and having a vertical center pi-n at the lower end thereof, a horizontal beam carried by said member, block's slidable'on said beann'clampin-g screws extending through one side of said blocks and engaging said beam for looking said blocks in their adjusted posit'ions, means for preventing said blocks from rotating on said beam, the lower portions of said blocks and having upright sockets therein, cutters having their upper ends disposed in said "sockets, screws extending diagonally through the 'lower portions of said blocks and engaging the upper vends of said cutters for adjusting the same, and additional screws extending horizontally through the lower portions of said blocks and engaging said cutters for locking the same in their adjusted positions.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
